"Going into closed-door training?" Su Yang was surprised. Why the need for closed-door training after advancing?
"The power we've accumulated in the Fusion Realm must be completely converted to the Land Immortal Realm's power once we reach the Land Immortal Realm," Mahakaya said. "This conversion requires time. The more power accumulated in the Fusion Realm, the more needs to be converted upon reaching the Land Immortal Realm, thus extending the time needed."
"How long will it take?" Su Yang asked incredulously.
Mahakaya thought for a moment: "At least two years!"
Su Yang couldn't help but feel shocked; that timeframe was indeed lengthy.
But upon reflection, it was inevitable.
The four Beigong War Gods had accumulated an immense amount of power in the Fusion Realm. Once they advanced, it was indeed significant.
Moreover, the key point was, keeping them in the Fusion Realm would be a waste.
